No. It's a perfectly relevant test of your consistency, or lack thereof. The US Constitution acknowledged slavery was an institution in congressional apportionment counting and barred any amendment banning the import of slaves until 1808. Slavery was indisputably present in the U.S. Constitution, yet you said that "Any nation that had slavery incorporated into its founding constitution was in no way correct."
So my question to you. The US Constitution incorporates slavery in several clauses. Does that mean it is "in no way correct"?
Answer it and show your inconsistency. Avoid it and show your foolishness. Either way, the flaw in your earlier reasoning is exposed.
The Articles of Confederation are (is?) our founding Constitution, not that pact with the Devil out of Philadelphia.
